The High Efficiency
Antenna System produces a signal
intensity, which, with
FCC allowance, is higher
than possible using the
standard antenna system
(linked below). At 10 watts, the
signal intensity may be
2.0 mV/m at 2.25 miles,
producing a sign-able
range of 8 to 12 miles.
(Note: Special FCC allowance
for increased signal
intensity is required.)

The High Efficiency
Antenna System's
49-foot antenna/tower,
antenna tuner and
30-foot groundplane are
designed to be
ground-mounted in an
unobstructed area
approximately 100 feet
in radius for maximum
propagation. A concrete
pad supports the
antenna, tower and
tuner.

Components

Antenna TowerThe tower is 21” square
at the top and base and
48” high. It is a
one-piece, galvanized
steel tower with a
hinged bottom plate that
allows the tower to
“tilt-down” to a
90-degree angle during
antenna setup and
erection. The tower
includes a side mount
for the antenna tuner.
The antenna bolts to the
tower through the
tower’s top plate.

Antenna Tuner System

Provided in a
weatherproof NEMA4
cabinet, the High
Efficiency Antenna
System tuner features
tuning networks for both
resistive and reactive
components, lightning
arrestor and ground bus
on an aluminum panel.

Groundplane

A groundplane is the
copper wire part of the
antenna system buried
beneath the antenna
support. The PowerPlaneTM
Groundplane is placed in
a 6” to 12” excavation
that extends outward 30’
in all directions and is
covered with backfill.
The groundplane consists
of two central arcs of
#4 bare stranded copper
wire with 80 radials
that extend outward in a
circular pattern,
provided in two halves
for convenience.
